Figure 6.15 | Global mean surface air temperature (GSAT) response to an abrupt reduction in emissions (at time t=0) of idealized climate forcing agents with different lifetimes. All emissions are cut to give a radiative forcing of –1 W m^–2 at a steady state (except for CO₂). In other words, if the yearly emissions are E₀ before the reduction, they will have a fixed lower value E_year>0= (E₀– δE) for all succeeding years. For comparison, the GSAT response to a sustained reduction in CO₂ emissions resulting in an RF of –1 W m^–2 in year 100 is included (dashed line). The temperature response is calculated using an impulse response function (Cross-Chapter Box 7.1) with a climate feedback parameter of –1.31 W m^–2°C^–1. Further details on data sources and processing are available in the chapter data table (Table 6.SM.3).
